Hold on tight to the popcorn and make sure that soda is secure in its holster because the moviegoing experience is going for a ride.

The Pruneyard’s Camera 7 Cinemas is pushing for a more interactive theater experience, and the latest addition is in the seats. The theater is set to unveil 22 new D-BOX MFX seats that are in sync with what’s happening on the screen, providing real-time motion and another dimension to watching movies.

The technology may not surprise anyone who’s ever been to a theater attraction at a theme park, but Camera Cinemas officials insist this is different than any other experience. The theater has a couple demo seats sitting in its lobby, but the official release of the seats will take place during the premiere of the Warner Bros. movie Inception on July 16.

While theme park rides may simply jerk passengers up and down and from one side to the other, D-BOX is a bit more subtle, said Guy Marcoux, vice president of marketing for the Montreal-based company. D-BOX works closely with movie studios during the production of films to ensure that even the smallest detail is captured in the movement of the seats.

It can be as subtle as the bumps on a car ride when a vehicle goes off road or as intense as an action sequence’s explosions and crashes. Marcoux said it could take anywhere from 300 to 500 hours to encode just one film. And because the motion is synchronized to the millisecond, there’s hardly any lag time between what’s seen on the screen and what’s felt in the seats.

“This is more subtle and refined,” Marcoux said. “We’re not there to jolt you around.”

Each seat is equipped with volume controls and an “intensity switch” with three settings and an off button, so individuals will be able to select exactly how much they want to be moved around during the course of a movie. The soundtrack is also separate from the theater’s speakers and instead comes from speakers installed in the seats.

Developed for home entertainment, D-BOX seats first started popping up in theaters in April 2009 and are compatible with about 15 films so far. After Inception, other releases this year include The Expendables and TRON.

There are 30 theaters in the United States and Canada that have D-BOX seats, and Camera 7 is the first in Silicon Valley to install the technology, according to Marcoux, who cites a 91 percent approval rating from those who have experienced D-BOX in theaters.

“We’re trying to create motion effects and intelligent vibrations that move your seat with what’s happening on the screen,” Marcoux said. “The way to do that is to really work hand in hand with studios. If it was a gimmick, movie studios would not associate with us.”

The Pruneyard’s theater has traditionally been associated with patrons who prefer art house films, but it can also be a place that features the latest in theater technology, said Alejandro Adams, general manager of Camera 7. Whether customers find it worth it remains to be seen. The cost of a D-BOX seat is $8 on top of the price of the movie ticket.

“We’ve continued to try to meet the needs of every moviegoer of every stripe, and this was just a development that is best suited for the cinema of tomorrow,” Adams said, adding that the theater is “not moving toward a more interactive experience at the expense of higher culture.”

Camera 12 in San Jose is next in line to have motion seats, Adams said. Camera Cinemas has moved to the front of the line in incorporating new technology to the moviegoing experience in recent years.

Last year, Camera 7 rolled out four new Sony 4K digital projection screens designed to provide four times better quality than the standard high-definition television. The Campbell theater also turned some of its screens into a forum for video game release parties and a place for pre-movie entertainment.
